DEFINITION
RW 0x3C
DAC Right Channel Volume
Set the Right channel DAC volume with 0.5017 dB steps from
0 to -90 dB
0x3B and less = Reserved
0x3C = 0 dB
0x3D = -0.5 dB
0xF0 = -90 dB
0xFC and greater = Muted
If VOL_RAMP_EN = 1, there will be an automatic ramp to the
new volume setting.
RW 0x3C
DAC Left Channel Volume
Set the Left channel DAC volume with 0.5017 dB steps from 0
to -90 dB
